- Referring to
FIG. 1 , a cable management panel ormodule 10 according to the present invention is shown. Thepanel 10 includes a frame orchassis 12 havingmounting brackets 14 used to mount thepanel 10 to a telecommunications structure, such as a telecommunications rack (only partially and schematically represented at 15). Thecable management panel 10 can also be configured for mounting within a cabinet, enclosure, or on other mounting fixtures or framework. - Referring to
FIGS. 1 and 3 , thechassis 12 of thecable management panel 10 generally has afront 16 that defines a front opening 17 (see alsoFIG. 2 ),opposite sides 18, and a rear 20. Thesides 18 are defined bysidewalls 22, and the rear is defined by arear wall 24. Thechassis 12 further includes atop wall 26 and anopposite bottom wall 28. The front opening 17 may be enclosed by afront cover 74. In the illustrated embodiment, the front cover 74 (FIG. 2 ) is hinged to thebottom wall 28. A front latch 76 (FIG. 1 ) is provided to secure thefront cover 74 in a closed position. - Referring now to
FIG. 3 , thecable management panel 10 includes a least onedrawer 30 that slides between an opened position and a closed position. In the opened position, cables and components contained on thedrawer 30 can be accessed for maintenance or repair purposes, for example. In the closed position, the cables and components are enclosed and protected within a non-partitionedinterior region 32 of thechassis 12. What is meant by “non-partitioned” is that theinterior region 32 is open and generally non-obstructed by a dividing wall or panel, for example. - Referring now to
FIGS. 2 and 3 , thechassis 12 of thecable management panel 10 of the present disclosure includes a first pair ofdrawer guides 34 and a second pair ofdrawer guides 36. The first and second pairs ofdrawer guides interior region 32 of thechassis 12. In the illustrated embodiment, each of the pairs ofdrawer guides structures 38 attached to thesidewalls 22 of the chassis. The channeledrails 38 are aligned and arranged to define an upper pair of channeled rails (e.g., 34) and a lower pair of channel rails (e.g., 36). - Referring to
FIGS. 3 and 4 , thesliding drawer 30 of thecable management panel 10 is engaged with one of the first and second pairs ofdrawer guides drawer 30 relative to thechassis 12. In particular, thedrawer 30 includes a drawer bottom 40 (FIG. 4 ) andupright sides 42 that extend upward from thedrawer bottom 40. Theupright sides 42 engage the channeledrails 38 of the upper or lower pair ofdrawer guides - The non-partitioned
interior region 32 of thechassis 12 is sized and constructed to receive two one-rack-unit drawers, as shown inFIG. 3 . A “rack unit” is known to those of skill in the art generally as a standard unit of volume within a telecommunications rack. The size of equipment can be referred to by the number of rack units occupied by that piece of equipment. InFIG. 3 , eachindividual drawer 30 occupies a single rack unit; thechassis 12 of thecable management panel 10 is sized to receive two of the one-rack-unit drawers 30. As can be understood, theupright sides 42 of the upper drawer engage the channeled rails 38 of the upper pair of drawer guides 34 and the upright sides of the lower drawer engage the channeled rails 38 of the lower pair of drawer guides 36. - The non-partitioned
interior region 32 of thedrawer 30 is also sized and constructed to receive one two-rack-unit drawer 130, as shown inFIG. 2 . When a two-rack-unit drawer is installed within thechassis 12, theupright sides 142 of the drawer (e.g., 130) engage the channeled rails 38 of the lower pair of drawer guides 36. The channeled rails 38 of the upper pair of drawer guides 34 have a low profile so as not to obstruct receipt and sliding movement of the two-rack-unit drawer 130. - Referring now to
FIGS. 4-6 , thecable management panel 10 further includes aspring lock clip 44. In the illustrated embodiment, thepanel 10 includes two spring lock clips 44 that are carried by thedrawer 30 during sliding movement of the drawer. The spring lock clips 44 are secured to theupright sides 42 of thedrawer 30. - Each
spring lock clip 44 has a first tab end 46 (FIG. 5 ) and asecond tab end 48. The tab ends 46, 48 partly extend through breaks or openings in theupright sides 42 of the drawer. Thefirst tab end 46 engages a first aperture 50 (FIG. 3 ) formed in the chassis when the drawer is in the open position. Thefirst tab end 46 defines a positive mechanical lock that locks the drawer in the open position to prevent inadvertent closing movement while accessing the drawer interior. To unlock thedrawer 30 from the locked opened position, the first tab ends 46 of theclips 44 are press inward until disengaged from thefirst aperture 50; the drawer is then free to slide toward the closed position. As shown inFIG. 3 , the positive mechanical locks defined by theapertures 50 and first tab ends 46 of theclips 44 are located adjacent to thefront 16 of thechassis 12 for access from an exterior of thechassis 12. - The
second tab end 48 of eachspring lock clip 44 engages a second aperture 52 (FIG. 3 ) formed in the chassis when the drawer is in the closed position. Thesecond tab end 48 defines a friction-type lock that holds the drawer in the closed position to prevent inadvertent opening movement. Thesecond tab end 48 is constructed such that to open thedrawer 30 from the closed position, the user simply pulls the drawer forward. The pulling force overcomes the frictional hold of thedrawer 30 and disengages thesecond tab end 48 of thespring lock clip 44 from the second aperture 52; the drawer is then free to slide toward the open position. - Referring still to
FIGS. 4-6 , thecable management panel 10 further includes acable manager 54 that accommodates cable slack during sliding movement of thedrawer 30 relative to thechassis 12. Thecable manager 54 includes aradius limiter 56, a floating attachment piece 58 (FIG. 5 ), and astationary plate extension 78. Theradius limiter 56 is attached toprojections 80 formed on the floatingattachment piece 58. The floatingattachment piece 58 is in turn slidingly attached to thestationary plate extension 78 through aslot 64 form in thedrawer bottom 40. Theradius limiter 56 of thecable manager 54 has acurved body structure 82 that also protects cables from damage by limiting cable bending beyond a minimum bend radius. - Referring to
FIGS. 5 and 6 , theplate extension 78 is located beneath thedrawer 30. The floatingattachment piece 58 is slidingly attached to aslot 84 formed in theplate extension 78. Theplate extension 78 remains stationary relative to thechassis 12 during sliding movement of thedrawer 30; theslot 84 of theplate extension 78 and theslot 64 of the drawer bottom 40 permit theradius limiter 56 to slide and/or float along the drawer bottom 40 as needed to accommodate cable slack during movement of thedrawer 30. What is meant by “float” is that theradius limiter 56 is able to move independently of the drawer and relative to the chassis within a range of motion as needed to accommodate the pull or push of cables wrapped about the radius limiter. The range of motion is determined in part by theslot 84 of thestationary plate extension 78 which functions to limit the movement of theradius limiter 56 and in turn permits thedrawer 30 to slide relative to theradius limiter 56. Further details of a radius limiter arrangement having a similar slotted, stationary cable manager component are described in U.S. Pat. No. 5,066,149; which disclosure is incorporated herein by reference. - Referring to
FIGS. 3-5 , a releasable latch 66 (FIGS. 4 and 5 ) is provided at afirst end 60 of thestationary plate extension 78. Thefirst end 60 of thestationary plate extension 78 is attached to thechassis 12 by thereleasable latch 66. In particular, thelatch 66 extends through anopening 68 formed in therear wall 24 of thechassis 12. Opposing flexible latch arms 70 snap-fit to theopening 68 of the chassis. Thelatch 66 secures theplate extension 78 in a stationary position for purposes of causing the relative movement between thedrawer 30 and theradius limiter 56, as described above. The latch also prevents inadvertent separation of thedrawer 30 from thechassis 12. - The
latch 66 is accessible from an exterior of thechassis 12, and is releasable so that the slidingdrawer 30 can be selectively separated from thechassis 12. To separate and remove thedrawer 30 from thechassis 12, the latch arms 70 of thelatch 66 are flexed toward one another to disengage therear wall opening 68. - Referring again to
FIG. 4 , thecable management panel 10 can include a variety ofcable connections 72 that provide or accommodate telecommunications service. In the illustrated drawer embodiment, thecable connections 72 include integrated cable terminations and splice connections. The splice connections can include one or more stackablesplice tray modules 88. The cable terminations can include sliding adapter packs ormodules 86 having adapters that receive fiber optic connectors. Further details of an example sliding adapter arrangement that can be used in accordance with the principles disclosed are described in U.S. Pat. No. 5,497,444 and U.S. Pat. No. 6,591,051; the disclosures of which are hereby incorporated by reference. In the illustrated embodiment ofFIG. 4 , thesplice tray modules 88 and adapter packs 86 accommodate up to 24 cable connections or terminations; accordingly a panel having two one-rack-unit drawers 30 accommodates up to 48 cable connections. - As can be understood, the present
cable management panel 10 can be configured to provide a number of cable connection configurations, including 12, 14, 48, 72 and 96 termination configurations. As can also be understood, thepresent drawer 30 can be configured to provide only cable terminations, only cable splicing, or a combination of terminations and splicing. Other drawer configurations can further include attenuators, couplers, switches, and wave division multiplexers (WDMs), for example. - Referring still to
FIG. 4 , thecable management panel 10 can also include a variety ofcable management elements 62 that provide bend radius protection for use with fiber optic cables. Thecable management elements 62 can include, for example, a rear spool 90 (FIG. 3 ) and an array of front guides 92. As will be described in greater detail hereinafter, therear spool 90 manages cables entering at or adjacent to the rear 20 of thechassis 12, and the array of front guides 92 manages cables exiting at or adjacent to thefront 16 of the chassis. Other cable guides, e.g., 94, are positioned at various locations on thedrawer 30. - Referring again to
FIG. 3 , cables connected to thecable connections 72 access theinterior region 32 of thechassis 12 by any one of a number of access locations defined by thepresent chassis 12. The number of access locations includes first and secondrear access openings 96 formed in therear wall 24 of thechassis 12. In the illustrated panel ofFIG. 3 , the first and secondrear access openings 96 correspond to the first and second one-rack-unit drawers 30. - Another access location of the chassis is defined by a rear side access opening 98 formed in one of the
opposite sidewalls 22 of the chassis adjacent to therear wall 24. Still other access locations include first and second frontside access openings 99 provided at each of theopposite sidewalls 22 adjacent to thefront opening 17 of the chassis (see alsoFIG. 1 ). - Referring now to
FIGS. 7 and 8 , the number of access locations defined by thechassis 12 of the presentcable management panel 10 accommodates a variety of cable routing alternatives. As shown inFIG. 7 , for example, in one routing configuration, anincoming cable 61 enters the rear access opening 96 (FIG. 3 ) and is guided around therear spool 90 toward thecable manager 54. Thecable 61 wraps about theradius limiter 56 of thecable manager 54 and is directed toward the other cable guides 94 located adjacent to thesplice tray modules 88. The cable is spliced and theindividual fiber cables 63 of theincoming cable 61 are routed toward and attached to rear connection ends of theadapter modules 86.Fiber cables 65 attached to front connection ends of theadapter modules 86 are routed within the front guides 92 and into achannel 93 located between the array of front guides 92 and a front drawer wall 29 (see alsoFIG. 4 , for example). Thefiber cables 65 exit thedrawer 30 and the chassis through one of the frontside access openings 99, depending upon the desired orientation of the array of front guides 92. In the illustrated embodiment,curved exit devices 25 are provided on the drawer to prevent the exitingfiber cables 65 from exceeding a minimum bend radius. - In the alternative, and referring to
FIG. 8 , another routing configuration may include routing theincoming cable 61 through the rear side access opening 98. In this routing configuration, theincoming cable 61 is guided around therear spool 90 in an opposite direction as the previous routing configuration. The incoming cable is then similarly routed to thecable manager 54, about theradius limiter 56 of thecable manager 54, and then toward the other cable guides 94 located adjacent to thesplice tray modules 88. The cable is likewise spliced and theindividual fiber cables 63 of theincoming cable 61 are routed toward and attached to rear connection ends of theadapter modules 86.Fiber cables 65 attached to front connection ends of theadapter modules 86 are routed within the front guides 92, into thechannel 93, and exit thedrawer 30 and the chassis through one of the frontside access openings 99. As can be understood, either routing configuration may be used in both the one-rack-unit drawer 30 and the two-rack-unit drawer 130. - As previously described, the non-partitioned
interior region 32 of thechassis 12 is sized and constructed to receive two one-rack-unit drawers (FIG. 3 ) or one two-rack-unit drawer 130 (FIG. 2 ). Referring toFIGS. 9-11 , one embodiment of the two-rack-unit drawer 130 is illustrated. - Similar to the one-rack-unit drawer, the two-rack-
unit drawer 130 carries two spring lock clips 44 that attach to theupright sides 142 of the drawer. The spring lock clips function as previously described to lock thedrawer 130 in the open position and to hold the drawer in the closed position. Also similar to the previous drawer embodiment, thedrawer 130 has a drawer bottom 140 (FIG. 10 ) that defines aslot 164. Thecable manager 54 is mounted at theslot 164 to accommodate cable slack during sliding movement of thedrawer 130, as previously described. - Referring to
FIG. 10 ,cable connections 172 including integrated cable terminations and splice connections are provided on thedrawer 130. The splice connections includes one or more stackablesplice tray modules 188. The cable terminations include sliding adapter packs ormodules 186 having adapters that receive fiber optic connectors. In the present embodiment, thesplice tray modules 188 and adapter packs accommodate up to 96 cable connections or terminations. - Referring now to
FIG. 12 , another embodiment of a two-rack-unit drawer 230 is illustrated. In this embodiment, thedrawer 230 is loaded with twelvetermination modules 286. Thetermination modules 286 define rear connection locations to which incoming cables are directly coupled. Theindividual termination modules 286 can each be configured to house various fiber optic equipment including couplers, splitters, combiners, wave division multiplexers, etc. - In some high-density applications having a two-rack-unit drawer, cables may be routed through both the upper and lower
rear access openings 96. In such applications, the panel may includestacked spools 90, as shown inFIG. 12 , to accommodate the two rear cable entry locations. Such drawers may also include acable manager 54 having stackedradius limiters 56. - In general, the present cable management panel includes a
chassis 12 that can be utilized to provide a variety of fiber termination/distribution arrangements. The advantageous flexibility of the present panel is due in part to the construction of thechassis 12. In particular, and referring now toFIG. 13 , during an initial installation period, a user may populate atelecommunications rack 15 or frame with a number of empty cable management panels 10 (i.e.,empty chassis 12 with no drawers).Drawers - For example, the user can install a single one-rack-
unit drawer 30 to add capacity for 24 terminations, install two one-rack-unit drawers 30 to add capacity for 48 terminations, install a two-rack-unit drawer to add capacity for 96 terminations, or install a combination of any of these drawers when the user deems such capacity is required. Further, the drawers can be pre-configured with splice only, termination only, or a combination of slice and terminations during manufacture for quick installation at the user's facility. What is meant by “pre-configured” is that the desired cable connections (e.g., 72) and the cable management elements (e.g., 62) are mounted to or loaded on the drawer at the factory, as opposed to at the user's facility. To install a drawer, the user simply slides the pre-configured drawer into the chassis and snap-fits the rear latch (e.g., 66;FIG. 5 ) to the chassis. As can be understood, thechassis 12 of the present disclosure is constructed to accommodate a variety of drawer configurations, which allows a user to grow a telecommunications system in a unique customized manner. - Referring to
FIG. 14 , another embodiment of a cable management panel ormodule 410 according to the present invention is illustrated. Thepanel 410 includes a frame orchassis 412 having mountingbrackets 414 used to mount thepanel 410 to a telecommunications structure, such as a telecommunications rack (schematically represented at 15 inFIG. 13 ). In the illustrated embodiment and referring toFIG. 15 , the mountingbrackets 414 are L-shaped and constructed to mount to either a rack having a 19-inch mounting configuration or a rack having a 23-inch mounting configuration. In particular, the mountingbrackets 414 each include afirst flange portion 431 and asecond flange portion 433. When mounted to a rack with a 19-inch mounting configuration, thefirst flange portion 431 is secured to thechassis 412 and thesecond flange portion 433 is secured to the rack. When mounted to a rack with a 23-inch mounting configuration, thesecond flange portion 433 is secured to thechassis 412 and thefirst flange portion 431 is secured to the rack. Thecable management panel 410 can also be configured for mounting within a cabinet, enclosure, or on other mounting fixtures or framework. - Referring to
